Abstract
Alemtuzumab is a lymphocyte-depleting humanized monoclonal antibody that targets CD52 and binds to T and B lymphocytes, macrophages, monocytes and natural killer cells.1 It was approved decades ago for the treatment of B-cell chronic lymphocytic leukemia (CLL), and the use of alemtuzumab in kidney transplantation was first described in the late 1990s as a drug that could promote tolerance and allow for maintenance drug minimization.2 Although there has been variability in dosing in renal transplantation3-5, alemtuzumab is typically administered at a dosage of 30 mg intravenously once or twice in the perioperative transplant period, which is a fraction the cumulative dosage used for CLL. Its usage in kidney transplantation remains off label. This article is protected by copyright. All rights reserved.
